Just anecdotally, increasing the blur seems to have an associated performance cost, especially in Springboard ("the home screen".) It's probably only ~100ms for each interaction, so it probably won't impact latency-insensitive users.

As others have said, it helps with the legibility but Liquid Glass is still distracting and illegible. I share the wish that Apple eventually returns to a more sensible, legible UI.
